For some time I was thinking about recording some gameplay footage. Mostly older titles lets say up to year 2002. At first I was almost determined to buy Aver Game Broadcaster HD (C127) which seemed to be very good - VGA and HDMI input, no onboard h264 encoder, perfect. Well, that thing was for sale at ~ $120 which is not very cheap. Anyway before I decided whether to buy or not, this Aver became EOL.
That is unfortunate... but later I realized my original plan to upload ultra-HQ videos with maxed out AA/AF would be ruined by very poor youtube re-encoding. So no point in investing that much money in capture HW. To demonstrate how much youtube decrease video quality you can compare the this H264 source footage http://hw-museum.cz/data/pctf/Mig-15bis_RB.mkv and how youtube turn it into ugly blury something. https://www.youtube.com/watch?v=5eXNH72O_Yk&feature=youtu.be
So I figured maybe S-Video capture would provide sufficient quality while keeping price of such solution reasonable. Obviously two computers are needed for this, which is no problem for me.
Source should be appropriate CPU + MB for intended game + one of the following video cards:
Rage II PCI
Virge GX2
Rage Pro
Matrox G200
Savage 3D
Rage 128 Pro
Riva TNT2
Radeon (R100)
Radeon 8500
GeForce2/3/4
Voodoo Rush
Voodoo2/3/4
(I have all these available with S-Video output)
And the recording side... here comes the tricky part where I'm not so sure. Ebay is flooded by these USB grabbers http://www.ebay.com/sch/i.html?_from=R40&_trk … re&_sacat=58058 Basically there are two types. The cheaper one supports S-Video and composite. And the other type also support component video input.
1. what is the raw output of these USB grabbers? Uncompressed video or there is some kind of built-in encoder? 640x480x24 @ 30fps uncompressed video results in almost 30 MB/s... which is pushing USB 2.0 to its limit.... not to mention higher resolution.
2. IIRC the component input should provide better quality but I doubt any of the video cards mentioned above can work with passive VGA -> RGB cable.
3. Considering this maybe it would be better to simply use one of my AIW Radeons or other video card featuring VIVO function. And some decent audio card for sound recording - should provide better quality than USB grabber.
Do you think S-Video capture quality is good enough to record games like Doom, glide accelerated NFS3, UT, etc?
